    Summary
    This summary is machine-generated.

    Contrast sensitivity is significantly reduced in open-angle glaucoma patients. Ocular hypertension patients with visual field changes also show decreased contrast sensitivity, highlighting the Cambridge low-contrast lattice test

    Area of Science:

    • Ophthalmology
    • Visual Neuroscience

    Context:

    • Open-angle glaucoma and ocular hypertension are common optic neuropathies.
    • Assessing visual function beyond acuity is crucial for early detection and management.
    • Contrast sensitivity is an important visual parameter affected in glaucoma.

    Purpose:

    • To evaluate contrast sensitivity using the Cambridge low-contrast lattice test in patients with open-angle glaucoma and ocular hypertension.
    • To determine the correlation between contrast sensitivity deficits and visual field/optic disc changes in ocular hypertension.

    Summary:

    • A statistically significant decrease in contrast sensitivity was observed in patients with open-angle glaucoma.
    • In ocular hypertension patients, reduced contrast sensitivity was associated with concurrent visual field and optic disc alterations.
